Walmart-backed Flipkart said that around 3 per cent of orders have been cancelled due to "anomalies". The company did not reveal any further details.
The sellers, however, said that this usually happens during the sale. The website continues to take orders even if the demand exceeds the sales projections and supply. The orders are only cancelled if there is a shortfall in the supply of the products, they added.
During the ongoing festive sale, smartphone sellers are expected to sell phones worth $7.7 billion.
Also, as the demand exceeds the supply, the product may take weeks to get delivered. This, according to the sellers, may impact the quality of service and the reputation of the marketplace.
Cancellation of the orders happens "as marketplaces feel they won't be able to service them," Shilpi Jain, an analyst at CounterPoint research told ET.
